A fundamental assumption of models for the maintenance of genetic variation by environmental heterogeneity is that selection favours alternative alleles in different environments. It is not clear, however, whether such antagonistic pleiotropy is common. We mapped quantitative trait loci (QTLs) causing variation for reproductive performance in each of three environmental treatments among a set of 98 recombinant inbred (RI) lines derived from a cross between two D. melanogaster laboratory strains. The three treatments were standard medium at 25°C, ethanol-supplemented medium at 25°C, and standar

Mathematical modeling of non-isothermal flow of two-phase media in areas of complex geometric shape, which are often working units of various types of technological equipment, is considered. To construct a mathematical model describing the flow of a two-phase medium in channels and pipes of complex shape, the equations of conservation of mass, momentum and energy of the mechanics of multiphase media were used with the corresponding closing relations for the force of interphase interaction, the physical parameters of the two-phase medium and the rheological law of the state of the mixture in th

Photoplethysmography (PPG) is a commonly used in determining heart rate and oxygen saturation (SpO2). However, PPG measurements and its accuracy are heavily affected by the measurement procedure and environmental factors such as light, temperature, and medium. In this paper, we analyzed the effects of different mediums (water vs. air) and temperature on the PPG signal quality and heart rate estimation. To evaluate the accuracy, we compared our measurement output with a gold-standard PPG device (NeXus-10 MKII). The experimental results show that the average PPG signal amplitude values of the un

So its long term stability and durability is crucial to the electrochemical performance of fuel cell especially in an acidic, high temperature, humid environment. In present paper, the aging process of silicon rubbers has been studied in one simulated PEM fuel cell medium and two accelerated durability test (ADT) mediums for short time test at 70oC and 90oC, respectively.

We investigate thermoacoustic signals that are generated using an interstitial microwave ablation antenna powered by a microsecond pulsed microwave source. Two temperature regimes are examined: first, a spatially uniform temperature throughout the medium to experimentally validate the simulation model, and second, the realistic, spatially nonuniform temperature profiles that arise during microwave ablation.

Focusing on the micro range power size and low temperature heat sources, the ORC technology is still not mature due to the lack of appropriate machines and working fluids. Considering instead the medium to large size, the technology is already available but the investment is still risky. The intention of this thesis is to address some of th

Metal losses are disproportionately found within a poorly formed amorphous and semi-crystalline iron oxide phase analogous to ferrihydrite. This phase results from incomplete ferric hydrolysis and precipitation that occurs simultaneously with the leaching of the sulphide minerals. An investigation was conducted by ageing the residues at 95°C in water to assess the extraction of lost Cu and Ni and the transformation of ferrihydrite to the more crystalline goet

The principle hypothesis of this thesis is that hypoxia, in agar-based media, compromises rooting in vitro. From a practical point of view this is important because most plant tissue culture activities require the material to be successfully acclimatised in a nursery environment. Compromised rooting often results in excessive losses at this stage which are costly and inconvenient. In addition, many plants with commercial and/or scientific interest remain unavailable as they are not able to be rooted and acclimatised reliably. The use of agar as a rooting medium has limited the capacity of plan

Abstract The electrochemical corrosion behavior of X70 pipeline steel in the wall jet zone was investigated at high temperature and high pressure CO2 environment by jet impingement loop equipment with micro-electrode techniques. The corrosion morphologies and profiles of X70 steel after different corrosion times were characterized by Scanning Electron Microscope (SEM) and 3D optical measurement device. Results showed that the corrosion process of X70 steel was dominated by the anodic dissolution in the first 4 hours (4h), during which the highest corrosion rate was reached. With the increase o

Abstract The recent development of high strength corrosion resistant alloy UNS S42028 has opened up opportunities for the use of cost effective material solutions for applications such as high collapse liner sections in high pressure high temperature (HPHT) reservoirs. An important aspect with such a development in this application is an understanding of the environmental cracking behavior of Alloy UNS S42028 when exposed to clear brine fluids. This is particularly important during the completion phase of HPHT wells when medium density clear brine fluids are required. This paper will detail th

Abstract Supercritical water (SCW) is being considered as a cooling medium for the next generation nuclear reactors because it provides for high thermal efficiency and plant simplification. However, materials corrosion has been identified as a critical problem because of the oxidative nature of supercritical water. A number of Cr-containing ferritic and austenitic steels as well as Fe-Ni superalloys have been evaluated for corrosion in SCW environment at temperatures up to 600°C for exposure durations of up to 1000 hours. The ferritic steels developed a distinct two-layered oxide structure con

Abstract This research presents Phase 1 of a study for climate change impacts on the atmospheric corrosion of structural steel components of infrastructure such as bridges. ISO standards that provide quantitative models to calculate corrosion rate as function of key exposure parameters, namely, temperature, relative humility, chlorides, and sulfur dioxides are used in the evaluation, where the first-year corrosion rate is used to quantify and classify the severity of a corrosive environment. The corrosivity environment of six Canadian cities/locations for carbon steel bridges was modelled for

Electrochemical disinfection has gained interest as an alternative to conventional wastewater treatment because of its high effectiveness and environmental compatibility. Two and a half billion people currently live without improved sanitation facilities. Our research efforts are focused on developing and implementing a freestanding, additive-free toilet system that treats and recycles blackwater on site. In this study, we sought to apply electrochemical disinfection to blackwater. We compared commercially available boron-doped diamond (BDD) and mixed metal oxide (MMO) electrodes for disinfect

The species Chloridea virescens and Helicoverpa zea (Lepidoptera: Noctuidae) are declared agricultural pests with a high economic impact worldwide (Angulo et al. 2008). They are widely distributed on the American continent, and agrochemical are the most common method to control, which can cause environmental, social, economic and public impacts. A strain of Metarhizium rileyi Nm017 [AGROSAVIA - Orinoquia area (Col.)], demonstrated an e cacy of 75.8% on C. virescens, and 92.5% on H. zea on laboratory conditions. Mass production and virulence of Metarhizium sp. are susceptible to stress conditio

As the climate changes over the 21st century, the Puget Sound region's urban forest will be impacted by changing temperatures and precipitation regimes, leading to implications for the people who depend on its ecosystem services. This report summarizes climate change projections for the Puget Sound region and provides an assessment of tree species vulnerability in the region. We used projected shifts in plant hardiness and heat zones to understand how tree species of interest are projected to tolerate future conditions. We also assessed the adaptability of planted trees to stressors such as dr
